88LX2720 Data Sheet Introduction

IntroductionThe 88LX2720 is a programmable, high-performance Wave-2 G.hn AFE powerline communications with a single transmission channel and two reception channels to enable both SISO operation using one device and MIMO using two. In addition to the transmission and reception paths, the 88LX2720 contains a biasing circuit and a register block controlled from the digital interface.

Transmission path comprises a programmable transimpedance amplifier, a filter, and two line drivers to condition and amplify the OFDM signal from the DAC up to a level suitable for the wireline. Each reception path comprises an attenuator, a LNA, a filter, and a PGA to accommodate the signal from the wireline to a level suitable for the ADC range.

The operating mode of the 88LX2720 is highly configurable to balance performance and power consumption based on the requirements of bandwidth, power density, and physical medium.

The biasing block uses a bandgap reference generator adjusted with an external resistor to generate the biasing current and voltage for all the blocks of the circuit.

The digital interface is used to configure the register set from the baseband transceiver.

The 88LX2720 is supplied from 5V and 3.3V.

88LX2720 Data Sheet Typical Application

Typical ApplicationThe Wave-2 G.hn chipset (88LX5152 and 88LX2720) can be used in stand-alone or embedded applications. The typical applications are listed in the following subsections

Powerline-to-Ethernet AdapterThe powerline-to-Ethernet adapter is a standalone application containing the Wave-2 G.hn chipset (88LX5152 and 88LX2720), power supply, and Gigabit Ethernet interface in a single wall-plug box. MaxLinear provides reference designs implementing this application including Gigabit Ethernet and PLC MIMO modes, in which two 88LX2720 devices are used. This design can also be modified to use SISO only. In this case, only one 88LX2720 device is needed.

The following figure shows the block diagram of the powerline-to-Ethernet MIMO implementation.

88LX2720 Data Sheet WiFi Extender

WiFi ExtenderThe powerline-WiFi extender is a stand-alone application containing the G.hn chipset, a CPU, the power supply, and a WiFi access point in a single platform which is used to improve the coverage of wireless networks when the distance from a primary access point does not allow for an acceptable performance with the wireless end point. Placing this device including a secondary access point nearer the end point using power line as backbone provides significant improvement in this wireless link.

This application can implement Gigabit Ethernet interface, PLC MIMO, and any kind of IEEE 802.11 based WiFi access point. The design can be modified to use SISO only as well as to provide the backbone over coaxial or phone lines.

The following figure shows the block diagram of the powerline-WiFi platform example.

88LX2720 Data Sheet Digital Interface

Digital InterfaceThe 88LX2720 includes a 4-wire serial interface similar to SPI. The operation of this interface and the mapping of the registers is specifically designed to work with 88LX5152 and 88LX5153, therefore the information provided in this section is only informative and not intended to explain the use of this device in stand-alone mode.

■ Maximum clock frequency for write operations = 100MHz.

■ Maximum clock frequency for read operations = 25MHz.

■ Bit ordering within frames = MSB first.

The 88LX2720 supports two operating modes on the SPI interface:

■ Single input mode = In this mode only the SPI_IN pin is used to send information to the AFE chip. The SPI_OUT pin remains in high impedance during write operations and outputs data during read operations. This mode is equivalent to the standard SPI mode 3 (CPOL=1, CPHA=1).

Figure 7: Single Input Mode

■ Parallel input mode = In this mode the SPI_OUT pin becomes an input and works in parallel with SPI_IN, doubling the data rate and reducing the duration of the frame by half. The change to parallel input mode is configured in one of the registers during a previous single input transaction.

Figure 8: Parallel Input Mode

SPI_OUT remains in high impedance when SPI_NCS is not asserted. The biasing of the line is assured by the internal pull-up resistors of the AFE and the DBB devices.

When more than one AFE is used in a product, the SPI lines should be routed in a T shape with the branches reaching each device that has the same length.

88LX2720 Data Sheet Strapping Values

Strapping ValuesThe 88LX2720 AFE may operate in multi-AFE systems comprising one 88LX5152 DBB processor and one or more AFE IC’s all of them sharing a common SPI interface. To control each AFE IC separately a strapping value must be set externally to identify each AFE IC. This strapping value provides an internal identifier (2bits) for each AFE IC. This identifier must be used to compose the 6 bit address field of the SPI transaction.

Strapping is performed using VSEL pin which can be set to four different voltage values to define the device identifiers as listed in the following table.
